High-performance low-carbon concrete and preparation method thereof
The invention discloses high-performance low-carbon concrete and a preparation method thereof. The high-performance low-carbon concrete is prepared from the following raw materials in parts by weight: 360-520 parts of an integrated cementing material; 800 to 900 parts of fine aggregate; 1100 to 1200 parts of coarse aggregate; 7.0 to 9.0 parts of a water reducing agent; 160 to 180 parts of water; the integrated cementing material is prepared by uniformly dry-mixing the following raw materials in parts by weight: 35-40 parts of Portland cement clinker powder; 5 to 6 parts of high-calcium high-iron belite sulphoaluminate cement clinker powder; 5-10 parts of fine limestone powder; 14 to 20 parts of ground fly ash; 10 to 15 parts of superfine slag powder; 10 to 15 parts of steel slag micro powder; and 5-10 parts of coarse limestone powder. Compared with the traditional concrete, the low-carbon concrete disclosed by the invention has the advantages that the compressive strength of the C30-C60 grade concrete at each age is improved by 2-4MPa under the same using amount of a cementing material, the expansion degree is obviously increased, and the carbon emission strength of the concrete is reduced by 14.3%.
本发明公开了一种高性能低碳混凝土及其制备方法，由如下重量份原料组成：一体化胶凝材料：360‑520份；细骨料800‑900份；粗骨料：1100‑1200份；减水剂：7.0‑9.0份；水：160‑180份；一体化胶凝材料由如下重量份的原料干混均匀得到：硅酸盐水泥熟料粉35‑40份；高钙高铁贝利特硫铝酸盐水泥熟料粉5‑6份；细石灰石粉5‑10份；磨细粉煤灰14‑20份；矿渣微粉10‑15份；钢渣微粉10‑15份；粗石灰石粉5‑10份。本发明的低碳混凝土，相对传统混凝土，在同等胶凝材料用量下，C30‑C60等级混凝土各龄期抗压强度提高2‑4MPa，扩展度明显增大，混凝土碳排放强度降低了14.3％。
